I roughly translated it by cheating and using google, so my apologies if this is wrong:
Letter from Persephone Hades.
(it does not claim to be the original and correct according to the canons .. just written with love and from the heart)
"My spirit soars to you
I fly like a butterfly in darkness,
On the wings of only those that you gave me.
With light you lit my path.
In the past I could only see the dark dreams.
Full of death and destruction they were.
I am your vessel, I will fill you to the brim.
You are my soul, my flesh, my blood.
Nothing lasts forever but our love ... "
With eternal love, your Hades.
Such a beautiful love letter ^^ Altho I fear it isn't successfully translated ^^
Awesome image too
